SPECIFICATION forming' part O'f Letters :Patent N0. 684,544, datedOctober 15, 1901. Application led August 31, 1900. Serial No. 28.629.(No model.)

To all whom t may concern.-

Be it known that I, LOUIS GODDU, a citizen of the United States,residing at Winchester, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inVeltBeveling Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The present invention relates to an improvement in welt-bevelingmachines.

The object of the present invention is to produce a welt-lievelingmachine of simple construction and improved capacity for adv justmentand operation.

To the above end the present invention consistsin the welt-bevelingmachine hereinafter described, and particularly deiined in the claims.

In the accompanying drawings, illustrating the preferred form ofmyinvention, Figure l is a side elevation. Fig. 2 is a plan. Fig. 3 is afront elevation, and Figs. 4. and 5 illustrate details of constructionhereinafter described of my improved 4welt-beveling machine.

The machine consists generally of a workfeeding device, a work-gage, anda welt-bevcling knife. The knife and gage are fixed relatively to eachother and the work-feeding device,and the knife and gage are so arrangedand supported as to have motions toward and from each other toaccommodate themselves to the varying thicknesses of the work.

The frame l is provided with a socket 2, which is adapted to besupported by a suitable standard. (Not shown.) The workfeeding deviceconsists of a wheel 3, which is mounted in bearings in a lever 4,pivoted to the frame of the machine at 5. Upon the rear end of the shaft6 is mounted the gear 7, which is adapted to be driven -by the pinion 8,mounted on the short shaft 9 in the lower rear part of the frame of themachine. Suitable provision is made for rotating the pinion 8, as bymeans of the crank l0. The relative position of the gear 7 and thepivotal support for the lever 4 is such that the movement of the leverabout the pivot necessary` to compensate for varying thicknesses of workwill not materially alter the relative positions of the gear 7 and thepinion 8.

The work-feeding wheel 8 consists of two flanges l1, supported upon theshaft 6, having interposed therebetween a barrel 12. These parts areheld on the shaft by means of the bolt 13, screwed onto the end of theshaft. Between the two anges l1 and mounted upon the barrel l2 I placethe Work-engaging inaterial 14E, which I prefer to make of rubber.

Projected upwardly from the frame lis the knife and gage support 15. Thegage 16 is provided with a rectangular shank which is received in arecess cut in the top of support 15 and secured therein by means of thescrewebolt 17. The gage extends over the feedingswheel 3 and is adaptedto enter the crease between the upper and the welt, the end of the gagecontacting with the upper to position the work with relation to thetrimming-knife and the work being clamped between the surface of thefeeding-wheel 3 and the under side of the gage.

I8 designates the trimming-knife,consisting of a thin flat blade, and 19aholder therefor, consisting of a slotted cylindrical rod provided witha knurled head 2O at one end. The slot extends from end to end of therod and is open at one side, whereby the sides of the rod at each sideof the slot can be compressed to clamp the knife.

The holder 19 is adjustably held on the sup port l5 by means of a clampformed by suiti ably boring and slottinga projecting portion of thesupport, a screw-bolt 21 being provided for tightening the clamp. Theknife-holder is arranged so that its longitudinal axis extends at anangle to the line of feed, and the cutting edge of the knife extendstransversely to this axis. By loosening the bolt 2l the holder 19 may berotated to change the inclination of the edge of the knife with relationto the work, and the holder may also be moved longitudinally to bringthe knife-edge into proper position to give the desired depth of cut.The knife can be moved longitudinally in the holder to bring theknife-edge into position or to cause the knife to project a suitabledistance from the holder as the edge is worn away in sharpening.

For forcing the roll 3 toward the gage 15 to clamp the work I provide acoiled spring 22, seated in a hole boredin the socket 2 and pressingupwardly against the under side of the lever 4. A set-screw 23, on whichthe lower end of the spring 22 rests, serves as a means of adjusting thepressure exerted by the spring. A link 24, (shown in dotted lines, Fig.1,) pivoted on the pin 25, projecting from the lever 4 and connectingwith a treadle, serves as a means for depressing the roller 8.

In operation the roller 3 is depressed by the mechanism just describedand the edge of a shoe-sole inserted beneath the gage 16. The roller 3is now allowed to rise, and the edge of the sole is clamped between theroll and the under surface of the gage. The feeding-roller acts on thebottom of the sole and the gage on the upper surface of the welt, asclearly shown .in dotted lines in Fig. 1. As the shaft .6 is revolvedthe work is fed against the trimming-knife by the roll 3 and properlyguided bythe end of the gage 16 engaging the shoe-upper.

The thickness of the shaving cut from the welt and the inclination ofthe bevel edge produced will be determined by the position of the knife.To change the inclination of the bevel,theknifel1olderis rotated in itsholdingclamp, thereby adjusting the knife about an axis extendinglongitudinally thereof, and to vary the thickness of the shaving theknife or its holder is moved longitudinally ofvits axis,

ythe parts being secu rel y clamped in position after adjustment bymeans of the bolt 21.

It will be seen that by my invention I provide a simple and ef'cientmachine capable of a wide range of adjustment and capacitated foroperation upon many different styles of work.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A welt-beveling machine,having,in combination, Work feeding andguiding devices, a welt-beveling knife, the longitudinal axis of whichextends at an angle to the line of feed and the cutting edge of whichextends transversely to said axis, and means for holding the knifeconstructed and arranged to allow the knife to be adjusted angularlyabout said axis to change the angle and longitudinally thereof to changethe depth of the cut on the welt, substantially as described. j

2. Awelt-bevelingmachine,having,in combination, work feeding and guidingdevices, a knife-holder the longitudinal axis of which extends at anangle to the line of feed, a knifeblade held therein provided with acutting edge which extends transversely to said axis, and means forclamping theknife-holder constructed and arranged to allow theknifeholder to be adjusted angularly about said axis to change the angleand longitudinally thereof to change the depth of the cut on the welt,substantially as described.

3. A welt-beveling machine,having,in combination, work feeding andguiding devices,- a knife-holder comprising a cylindrical bar' thelongitudinal axis of which extends 'at an angle to the line of feed, aknife-blade held therein provided with a cutting edge which extendstransversely to said axis, and a clamp for the knife-holder constructedand arranged' to allow the knife-holder to be adjusted angularly aboutsaid axis to change the angle and longitudinally thereof to change thedepth of the cut on the welt, substantially as described.

4. A welt-beveling m'achine,having,in combination, a feeding-roller forengaging the bottom of a shoe-sole, a gage for entering the creasebetween the upper and the \velt,aknifeholder comprising a slottedcylindrical bar, the longitudinal axis of which extends at an angle tothe line of feed, and a clamp for the knife-holder constructed andarranged to allow the knife-holder to be adjusted angularly about saidaxis to change the angle and longitudinally thereof to change the depthof the cut on the welt, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
